Turbulence modelling of turbulent buoyant jets and compartment fires [PDF]

, 2001
Turbulent buoyant jets are a major feature in fire hazards. The solution of the Reynolds Averaged Navier-Stokes (RANS) equations through computational fluid dynamic (CFD) techniques allow such flows to be simulated.

An Observational Study of Low-Level Windshear at Hong Kong International Airport in Late Autumn and Early Winter

Atmosphere
Case studies of low-level windshear and turbulence encountered by aircraft with actual pilot reports under all sky conditions are conducted for the first time at Hong Kong International Airport (HKIA) for late autumn to early winter (October to December ...

Scalable Computation of Topological Abstractions for Scalar Data

Computer Graphics Forum, EarlyView.
Abstract Topological data analysis has become an important tool for large scale scalar data analysis and visualization, efficiently extracting the inherent structure and features of interest of the data. However, with growing dataset sizes and complexity, it is increasingly becoming infeasible to compute topological abstractions of interest in serial ...

Simulation of the Neutral Atmospheric Flow Using Multiscale Modeling: Comparative Studies for SimpleFoam and Fluent Solver

Atmosphere
The reproduced planetary boundary layer (PBL) wind is commonly applied in downscaled simulations using commercial CFD codes with Reynolds-averaged Navier–Stokes (RANS) turbulence modeling.

How Can Law Be Robust in the Face of Heightened Societal Turbulence?

Regulation &Governance, EarlyView.
ABSTRACT Taking its cue from the growing frequency of disruptive crises, new research argues that crisis‐induced turbulence calls for robust governance based on adaptation and innovation. While law plays a key role in the effort of governments to govern robustly, the robustness of law has received scant regard.

The underappreciated roles of fog and dew on vegetation and biocrusts

New Phytologist, Volume 251, Issue 1, Page 46-63, July 2026.
Summary Fog and dew represent minor components of ecosystem water budgets in most ecosystems. However, fog and dew can play an essential role in ecosystem dynamics and are particularly important for water‐limited systems. In addition to serving as direct water inputs, fog and dew can influence microclimate and water redistribution, thereby promoting ...

Nonlinear Extreme‐Heat Responses to the Spatial Progression of Deforestation in the Maritime Continent

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The Maritime Continent (MC) has undergone rapid deforestation in recent decades, altering its land‐atmosphere energy balance. Using idealized Community Earth System Model simulations, we examined heat extremes under progressively increasing deforestation extents, from localized coastal clearing to complete forest removal.

Mechanics of inhomogeneous turbulence and interfacial layers

, 2006
The mechanics of inhomogeneous turbulence in and adjacent to interfacial layers bounding turbulent and non-turbulent regions are analysed. Different mechanisms are identified according to the straining by the turbulent eddies in relation to the strength ...

Energy Dependence of Energetic Electron Precipitation Rates Near the Foot of Electron Isotropy Boundary

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract We report a rare quiet‐time observation by NOAA‐18 spacecraft flying nearly along the electron isotropy boundary (IBe). Complemented by data from four nearby meridional IBe crossings of other POES spacecraft, this case study provides a novel quantitative information concerning the regular energy dependence of the loss‐cone filling ratio (Jprec/
